image_types.bbclass: implement jffs2 summary images (sum.jffs2)
* Building the jffs2 filesystem to include summary information speeds up * the mount process considerably at the cost of increased size. * The rate of speedup is generally higher on NAND chips and on the chips * where the erase block size is large.
